Tankred

Tankred endures!

Tankred is a SPESS MEHREEN from the 40K Comic Damnation Crusade who, due to horrific injuries, must spend all his time in the metal shell of a Dreadnought. He is a member of the Black Templars.

He is in it for the bitches (and booze). His endurance is legendary.

He has been seen together with Fenix and has a rivalry with Grandfather Dreadnought.

Donovan, a Chaos Dreadnought working for the Iron Warriors, has repeatedly claimed to be the superior Dreadnought, but in every confrontation between the two thus far, Tankred has won by default.

TANKRED IS CANON!!!
Tankred is (subtly) mentioned in Imperial Armour 2's recent revision as Ancient Tahncred.
HE WAS ALREADY CANON!
